By Gail Tverberg: Debt: The Key Factor Connecting Energy and the Economy

Another insightful essay by Gail Tverberg…

There are many who believe that the use of energy is critical to the growth of the economy. In fact, I am among these people. The thing that is not as apparent is that growth in energy consumption is dependent on the growth of debt. Both energy and debt have characteristics that are close to “magic,” with respect to the growth of the economy. Economic growth can only take place when growing debt (or a very close substitute, such as company stock) is available to enable the use of energy products.

The reason why debt is important is because energy products enable the creation of many kinds of capital goods, and these goods are often bought with debt. Commercial examples would include metal tools, factories, refineries, pipelines, electricity generation plants, electricity transmission lines, schools, hospitals, roads, gold coins, and commercial vehicles. Consumers also benefit because energy products allow the production of houses and apartments, automobiles, busses, and passenger trains. In a sense, the creation of these capital goods is one form of “energy profit” that is obtained from the consumption of energy.

The reason debt is needed is because while energy products can indeed produce a large “energy profit,” this energy profit is spread over many years in the future. In order to actually be able to obtain the benefit of this energy profit in a timeframe where the economy can use it, the financial system needs to “bring forward some or all of the energy profit to an earlier timeframe. It is only when businesses can do this, that they have money to pay workers. This time shifting also allows businesses to earn a financial profit themselves. Governments indirectly benefit as well, because they can then tax the higher wages of workers and businesses, so that governmental services can be provided, including paved roads and good schools.

We can therefore restate this as when EROEI is high, debt growth depends on economic growth, and when EROEI is low, economic growth depends on debt growth.

There is a maximum limit to the ratio of debt to income, even at near zero interest rates.

This means we could not have built industrial civilization if the cost to extract fossil energy started out at today’s high level.

It also means that industrial civilization will collapse.

Another way to think of this is to recognize that debt is a claim on future energy. When total debt becomes larger than the available income can service, the debt defaults and becomes worthless. Which means the energy we expected in the future will not exist.

One thought on “By Gail Tverberg: Debt: The Key Factor Connecting Energy and the Economy”

“Forget about NAFTA or OPEC or TPP or crowd size or hand size or any other acronym or stat or concept that obsesses the financial press these days. Only two numbers actually matter.

The first is $20 trillion, which is the level the US federal debt will exceed sometime around June of this year.

To put $20 trillion into perspective, it’s about $160,000 per US taxpayer, and exists in addition to the mortgage, credit card, auto, and student debt that our hypothetical taxpayer probably carries. It is in short, way too much for the average wage slave to manage without some kind of existential crisis. “

For explaining why humans are odd
To Varki and Brower we applaud
A great mystery they solved
With denial we evolved
And created the Higgs, overshoot, and God

Denial not only makes us believe in god, it is god, because denial created us, and denial may destroy us.

The human brain, the God it believes in, and the overshoot it enabled and denies, all resulted from the same improbable genetic adaptation that occurred about 100,000 years ago.

Denial is the reality that must be most aggressively denied to avoid collapsing the house of cards that keeps us functioning.

The most amazing thing about human overshoot is that we do not discuss it.

You know you are in trouble when reduced CO2 emissions from an economic collapse caused by low-cost oil depletion is not sufficient to prevent civilization collapse from climate change caused by previously emitted CO2.

Our only choices are do we want to fall from a higher elevation later, or climb down from a lower elevation sooner?

Things that can’t continue usually stop too late.

Truth is like poetry and most people hate poetry.

All 8 billion of us owe our existence to a six-inch layer of topsoil and the fact it rains; 6 billion of us also owe our existence to nitrogen fertilizer created from natural gas by Haber-Bosch factories.

While it digs its own grave, all the mind can do is entertain fantasies and create excuses.

When the only paying job in town is sawing off the branch which you are sitting on, you….saw away! You might refuse to saw and hang yourself from that branch, but the end is the same anyway, and that option is much less fun. (Cynic @Megacancer)

It is remarkable that a brain emerged from a cloud of hydrogen and figured out the laws of physics that governed, and possibly made inevitable, its own creation and destruction.

We have met the oblivious and they are us.

All 8 billion of us originated from one small tribe in Africa about 100,000 years ago that gave birth to a child with an improbable mutation for a more powerful brain that denied reality. The other tribes were soon toast and we took over the planet. We’re all close cousins. I love you all. Except the deniers.

Meaning comes from understanding why we can understand there is no meaning.

Way too many smart people with big reputations are wrong about everything that matters. Something’s gonna happen that gives them an excuse not to have to admit they were in denial.

One of the most, if not the most, precious and rare things in the universe is the human brain. We have a cosmic obligation to use it and to confirm it works.

Fire to cooking to intelligence to denial to god to plotting to capital punishment to self-domestication to Apollo 11 to 7 billion too many.
